Emerson, Lake & Palmer performed on this day in 1977 at the Civic Arena in Pittsburgh, Pennsylvania.
A couple of concerts had had to be cancelled prior to this one, setting them back further financially. The financial issues which had plagued the band so far on this tour were worsened by the cancellation of a few dates.
I have been unable to find whether the orchestra was still with the band continuously at this point, though the decision had already apparently been made to let them go. It doesn’t seem that they were still with the group based on what I’ve yet found.
There is no known recording of this particular concert.
